Measure Functions

Use the measure tool to measure lengths, circles, areas, perpendicular distances and angles. Values are expressed in the same unit as the map.

Activate the measure toolbar by clicking the measure button in the top toolbar
Choose a measure function from the measure toolbar
1. Length and Area
  Click a series of points on the map view. The accumulative length and area (from the third point on) is calculated in real time and displayed in the measure toolbar. The measure indication is drawn on top of the map view. Right click the last point and choose “stop” or use the stop button to finish the measurement.
2. Circle Radius and Area
  Click once for the center and move your cursor around. The length (radius) and area (full circle) are calculated in real time and displayed in the measure window. The measure indication is drawn on top of the map view. Click again to fix the circle radius. Click one more time to start over.
3. Perpendicular Distance
  Click once at a first point of the help line, click once again at a second point of the help line. When the help line is set, automatically a perpendicular line is drawn. The perpendicular distance is displayed in the measure toolbar. Click once again to fix the perpendicular line. When you click the first time exactly at an already existing line, the help line is automatically drawn right on the existing line.
4. Angle
  The smallest angle between two lines will be calculated. First draw the first line by clicking at two points of the first line, then draw the second line by clicking at two points of the second line. The smallest angle between this two lines is then displayed in the measure toolbar. When you click the first time exactly at an already existing line, Orbit GIS will recognize this line and it will not be necessary to click twice to draw one line.
Clear the measurement by clicking or close the measure toolbar by clicking .
